HTTP Redirect: Hint or an example?

do you want redirection or rewriting?

Redirect vs. Rewrite

http://cheeso.members.winisp.net/iirf20Help/html/2e820208-c2eb-4d6d-a134-c63f7d41244f.htm

this is an example of redirection.

[root@ve1023:Active] config  b virtual bar list
virtual bar {
   snat automap
   pool server
   destination 172.28.19.79:8080
   ip protocol 6
   rules myrule
   profiles {
      http {}
      tcp {}
   }
}
[root@ve1023:Active] config  b rule myrule list
rule myrule {
   when HTTP_REQUEST {
   if { [HTTP::uri] equals "/ABC" } {
      HTTP::redirect "http://[HTTP::host]/DEF"
   }
}
}
[root@ve1023:Active] config  curl -I http://www.mydomain.com:8080/ABC
HTTP/1.0 302 Found
Location: http://www.mydomain.com:8080/DEF
Server: BigIP
Connection: Keep-Alive
Content-Length: 0

Hi Bertolazzi,

Try this:

 
when HTTP_REQUEST {
if { [string tolower [HTTP::uri]] starts_with "/abc" } {
HTTP::redirect [string map {"abc" "def"} [HTTP::uri]]
}
}

This iRule some assume that you just want to replace the sub-directory "abc" with "def" and keep the rest of the HTTP::uri.

If you are needing something else just let us know.

Hope this helps.

Nitass and Michael, tks for your reply!

 

 

I will test now and post the results.

 

 

Hi,

 

 

The redirection works fine with Nitass code!

 

 

Please, tell me if this configuration is correct:

 

 

http://www.mydomain.com:8080/ABC redirects to http://www.mydomain.com:8080/DEF and points to the pool pool_def

 

 

http://www.mydomain.com:8080/HIJ redirects to http://www.mydomain.com:8080/KLM and points to the pool pool_klm

 

 

when HTTP_REQUEST {

 

if { [HTTP::uri] equals "/abc" } {

 

HTTP::redirect "http://[HTTP::host]/def"{

 

"/abc*" {pool pool_def}

 

}

 

}

 

if { [HTTP::uri] equals "/hij" } {

 

HTTP::redirect "http://[HTTP::host]/klm"{

 

"/hij*" {pool pool_klm}

 

}

 

}

 

}

 

 

 

tks.

 

 

Hi,

 

 

I searched here in the forum and found a thread on redirection to pool, so I created two iRules.

 

 

1º - iRule - pool redirection

 

 

when HTTP_REQUEST {

 

switch -glob [string tolower [HTTP::uri]] {

 

"/abc*" {pool pool_def}

 

"/hij*" {pool pool_klm}

 

}

 

}

 

 

2º iRule - http redirection

 

 

when HTTP_REQUEST {

 

if { [HTTP::uri] equals "/abc" } {

 

HTTP::redirect "http://[HTTP::host]/def/"

 

}

 

if { [HTTP::uri] equals "/hij" } {

 

HTTP::redirect "http://[HTTP::host]/klm/"

 

}

 

}

 

 

I was successful in the tests that I performed, but i don't know if this way is the best.

 

 

I will continue performing the tests and keep everyone updated.

 

 

Tks.

i think Michael's irule is more general. by the way, you may combine two irules together.

e.g.

[root@ve1023:Active] config  b rule myrule list
rule myrule {
   when HTTP_REQUEST {
   switch [HTTP::uri] {
      "/ABC" { HTTP::redirect "http://[HTTP::host]/DEF" }
      "/HIJ" { HTTP::redirect "htt://[HTTP::host]/KLM" }
      "/DEF" { pool pool_def }
      "/KLM" { pool pool_klm }
   }
}
}

I tested with your iRule and worked.

 

 

Tks.
